Mechanical systems having anti-stick mediums applied thereto are provided. In one aspect, exhaust gas recirculation (EGR) valve systems having anti-stick mediums applied thereto are also provided. The anti-stick medium can be applied to any contacting surface, such as but not limited to the valve surface and/or the valve seat surface. The anti-stick medium is intended to prevent the valve surface and the valve seat surface sticking or bonding together, especially with respect to the operation of cooled or cold side EGR systems. If any materials should stick to the anti-stick medium, a portion of the anti-stick medium will break away from the surface, allowing the surface and/or component to function normally. The anti-stick medium can include, without limitation, boron nitride coatings, boron nitride aerosols, boron nitride greases, thin dense chrome platings, perfluoroalkoxy, and combinations thereof.

Exhaust gas recirculation valve

An anti-coking valve arrangement having a valve body that defines a passage for the flow of fluid medium. Valve seat and valve member positioned within the valve body and function to control the flow of fluid medium. A first anti-coking device is operably associated with the valve stem. A second anti-coking device is operably associated with the bearing guide member. A third anti-coking device is operably associated with the valve member and the valve seat. A fourth anti-coking device is operably associated with the valve stem and the bearing guide. A fifth anti-coking device is operably associated with the bearing guide. A sixth anti-coking device is operably associated between the valve stem and the bearing guide.

Valve having contamination counter-measures

A control module for controlling the operation of multiple fluid pressure actuated devices and electrical devices, as in an automotive heating/cooling system, includes a one-piece sheet metal frame or bracket upon which a plurality of solenoid valves, circuit boards and a manifold are assembled in a compact, tightly, but easily assembled, package. The assembled package is of a generally rectangular box-shaped configuration with electrical and fluid flow connections located at one end to connect with electric and fluid connectors fixedly mounted on the vehicle to provide a simple plug-in-type installation of the module on the vehicle assembly line.
